New Bacteria May Increase Peanut Yield | Rajkot News


RAJKOT: A new bacteria discovered at the University of Saurashtra not only promises to increase the yield of peanut crops, but also ensures a better quality harvest.
The results of the animal biotechnology department have been published in the famous international scientific journal “Nature”.
Anand Agricultural University also suggests that favorable bacteria prepared in the laboratory can significantly reduce the use of chemical fertilizers in peanut cultivation and also improve crop yield and soil condition.
According to the researchers, the main job of this biofertilizer is to maintain the condition of the soil and prevent the land from becoming barren in the long term. It works the same as cow dung in agriculture.
Groundnuts were chosen because it is a main crop in Saurashtra and the region is one of the largest peanut producers in the country. According to the article, the rhizosphere, a narrow area of ​​the soil near the roots of plants, is a hot spot for microbial activity. The rhizosphere microbiota directly or indirectly benefits plants by supplementing nutrients, producing beneficial chemicals, or suppressing pathogens. Plants attract and modulate bacteria in the rhizosphere by releasing exudates.
Plants also tend to select the rhizosphere microbiota according to their needs.
Ramesh Kothari, professor of microbiology at SU and co-author of this article, said: “Plant growth-promoting bacteria (PGP) like the bacillus have been enriched during the intermediate stages of crop development, but there has been a decrease in PGP organisms at the stage of mature culture. . Overall, this study described changes in the peanut rhizosphere microbiota during different stages of crop development and may help design stage-specific biostrategies, such as biofertilizers, to improve yield. cultures.
According to the article, many studies have examined the effects of soil type, geographic location, and crop genotypes, but very few have looked at changes in the microbiome throughout the crop development cycle.
Ankit Hinsu, a student in the department who did this laboratory research said, “It’s good for the soil if we can minimize the use of chemical fertilizers and move towards organic farming. For this, it is important to know which type of bacteria to insert at which stage. As the plant grows, the bacteria that help the plants change. We prepared a mixture of important bacteria after checking their properties and based on this study we suggested how much bacteria can be mixed in what amount at what stage to support the plant.
The sample of the peanut variety G-20 which is mainly grown in Saurashtra was used for the study.
